SlGH'i' FOR FIREARMS SPECiFICATION forming part of Letters Patent No.708,119, dated September 2, I902.

- Application filed May 18,1901. SBZ'iElNO. 60,798. (No man.)

To all whom it may concern:-

Be it known that I, JAMES TOMLINSON -BRAYTON, a citizen of the UnitedStates, and a resident of Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements in Sightsfor Firearms, of which the following is a specification. 7

My invention relates to sights for firearms,

sight as are likely to be met with in individual marksmen or sp0rtsmen.'2o To-these ends my invention consists, primarily,in a gun-sightcomprisinga double-convex lens mounted on the barrel and of sufficientfocal power to converge parallel rays of light to or'approximately tothe point of the" rear lens, the latter being a double-concave lens ofsuificient power to render parallel the rays of light converged by thefirst-named lens, thus giving at all times a clear and un blurred viewof the front sight and transmitting a clear and anerect image of'theobject aimed at to the eye of' the marksman.

The invention also consists in combining with the sight above outlinedmeans of adjusting the lenses to correspond to various imperfections orerrors of refraction with which the marksman may be affected, whetherfrom age or other causes; and the invention also consists of theeo'nstrnction, arrangement, and combination of parts, all

40 as hereinafter described and claimed;

In the-accompanying drawings, to which reference is made and which forma part of this specification, Figure 1 is a side elevation of arifiehaving myinvention applied thereto.

Fig. 2 is an enlarged plan/view showing one form of'the barrel-sight asa whole in its preferred form of construction; Fig. 3 rs a side view ofthe same located on the barrel; Figf 4,-an enlarged front view of theconvex lens.

Fig.1;- is-an enlarged sectional view of the rear concave lens; and Fig.6 1s a detailed lview of the pivoted or hinged frame, the main plate andlens-frame being shown in dotted lines. I

A represents an ordinarybead or pin-head sightmounted at the muzzle ofthe gun, and

B represents the rear sight, which is adapted to be tipped back to theposition shown in dotted lines or elevated, as desired. It comprises apost a and cup or eyepiece b, which carries a double-concave lens 0. Thecup or eyepiece, with'its lens,is vertically adjustable for range and isdetachable, so that it may be removed and replaced at pleasure. As hereshown, the vertical adjustment is effected by 05 a screw a, whichtelescopes the post a, and the eyepiece is detachably connected to thepost by a screw-shank b entering a screw threaded socket in the top ofthe post, as clearly shown in Fig. 5. I do not limit myself to this orto any special means for holding the eyepiece b, as various other meansmay be employed, all within the scope of my invention.

The eyepiece b, as here shown, consists of the annular andscrew-threaded disk d and the annnlarcompiemental cup d,formed-with' aninternally-screwthreaded flange (Z to match the screw-threads on theedge. of the disk (1. The double-concave lens 0 is provided with packing(l ,of felt or other suitable material, and is clamped firmly in the cupI) by screwing together the two parts thereof, or ratherby screwing thediskdint-o the flange d D represents a sight-plate secured to the barrelby a dovetailed groove l e, headed nut e, and screw e The rearportionfof this sight-plate is provided with an open-crotchsight g andis adjnstable'vertically y a screw g' orothersuitable meansfordifieretranges. On the said plate is mounted the double-convex lens h of suchpower as .to converge the parallel rays of light to the double-concavelens 0. The lens h is adjustable along the barrel to and from he lens 0and, as here 5 shown, is connected to'slide along the plate D, whichlatter is by preference formed with suitable'de'tents 11 2', suitablyspaced for different. adjustments. These detents, as here shown,aresmall sockets or indentations mad m in the plate D, with which a smallclick iengages; but I may dispense with the sockets and click or otherpositively-acting devic and rely upon friction for retaining the len atits various points of adjustment along the barreL- The means as a wholefor holding the lens h is composed of a bridge-piece 3',

formed with short upturned lugs It I; at its 'is pivoted or hinged in orto the short upturned earpiec'es or lugs 7t- 7;., so that thesight maybe tipped'down to a horizontal position when the gun is to be aimed.with open sights. Ifdesired, the plate-111" may be formed or providedwith an open sight n at right angles to 'the lens 71, inwhich case thecrotch-sight g may be omitted. The breech-sight 15, havingthesmallpeep-orifices,is,iu ell'eet,au ordinary sight plus tne double-concavelens, and with this the "t g necdnot be used unless de sired; but if thepeep-sight were omitted the sight 9 would be necessary for accurate aim.

Inasmuch as no niccty of construct-ion or adjustment need be applied tothe sight or lens 7:,ldo not limit myself to any special means ofattaeiunent, except in suclrclaims as are drawn to specific means. Ashere shown, the sight It may not only be adjusted along the barrel forrange and defecti e eyesight, but it may be detached from the gun andreplaced, so that the hunter may carry it in his pocket out of harms wayand place it on the gun at the moment, if needed.

'hile I have shown the diminishing-lens to be of. the double-concaveorder and the magnifying-lens to be of the double-convex order, I do'not limit myself to such types of lenses, as the known equivalents ofthese lenses may be used in place of the specific forms shown.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The combination with the front sight and a double-concave-lens sightat the breech, of a plate mounted on the barrel, a bridge adjustnblyconnected to the said plate, a frame hinged to said bridge and adouble-convex lens held in said frame, substantially as described.

2. A plate mounted upon the barrel,a bridge mounted to slide along saidplate, detonts for locking the said bridge to said plate and adouhloconvex lens mounted on said bridge, substantially as described.

The combination with the frontsightand a double-couvex-lens sight atthebreech, of a bridge adjustably mounted on the barrel, a

frame hinged to said bridge and a double-convex lens held in said frame.

42' The combination \viththe frontsightand a doublo-convex-lens sight atthe breech, of a bridge adjustably mounted on the barrel, a frame hingedto said bridge, said frame being providen with spring-clamps for holdinga double-convex lens, substantially as described.

5. In a sight for firearms a bridge adjustably mounted on the barrel,:1. tilting frame hinged to said bridge, a doubleconvex lens held bysaid tilting frame and an open sight adjacent to said tilting frame,substantially as described.
